Organization, Consolidation and Presentation of Financial Statements [Abstract]
Substantial Doubt about Going Concern [Text Block]	Note 2 – Going Concern A fundamental principle of the preparation of financial statements in accordance with GAAP is the assumption that an entity will continue in existence as a going concern, which contemplates continuity of operations and the realization of assets and settlement of liabilities occurring in the ordinary course of business. This principle is applicable to all entities except for entities in liquidation or entities for which liquidation appears imminent. In accordance with this requirement, the Company has prepared its accompanying Condensed Consolidated Financial Statements assuming the Company will continue as a going concern. We do not have adequate liquidity, including access to the debt and equity capital markets, to operate our business over the next 12 months from the date of issuance of this Form 10-Q. The Company had a working capital deficiency of $5.6 million as of March 31, 2018. As a result, our short-term business focus continues to be to preserve our liquidity position. Unless we are successful in obtaining additional liquidity, we believe that we will not have sufficient cash and liquid assets to fund normal operations and, as such, there is substantial doubt about the Company’s ability to continue as a going concern for the next 12 months from the date of issuance of this Form 10-Q. In addition, the Company’s obligations under its pension plan exceeded plan assets by $4.2 million at March 31, 2018, including $669,000 of minimum required contributions due over the next 12 months. The Company is in default on its 8¼% Limited convertible senior subordinated notes due 2012 (the “Notes”) and 9½% Subordinated debentures due 2012 (the “Debentures”), which have remaining principal balances of $387,000 and $220,000, respectively. Also, as of March 31, 2018, the Company was not in compliance with the fixed charge coverage ratio or loan turnover covenants related to its Credit Agreement (hereinafter defined), which non-compliance was waived by the Lender. As a result, if the Company is unable to (i) obtain additional liquidity for working capital, (ii) make the minimum required contributions to the defined benefit pension plan, (iii) make the required principal and interest payments on the Notes and the Debentures and/or (iv) attain and maintain compliance with all debt covenants, there would be a significant adverse impact on the financial position and operating results of the Company. The accompanying financial statements do not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amounts and classification of liabilities that may result from the outcome of this uncertainty. See Note 7 – Long-Term Debt for further details. The Company is seeking additional financing in order to provide enough cash to cover our remaining current fixed cash obligations as well as providing working capital. However, there can be no assurance as to the amounts, if any, the Company will receive in any additional financings or the terms thereof and the Company has no agreements, commitments or understandings with respect to any such additional financing. To the extent the Company issues additional equity securities, it could be dilutive to existing shareholders. In addition, the Company’s current outstanding debt and other obligations could limit its ability to incur more debt.

Note 2 – Going Concern

A fundamental principle of the preparation of financial statements in accordance with GAAP is the assumption that an entity will continue in existence as a going concern, which contemplates continuity of operations and the realization of assets and settlement of liabilities occurring in the ordinary course of business. This principle is applicable to all entities except for entities in liquidation or entities for which liquidation appears imminent. In accordance with this requirement, the Company has prepared its accompanying Condensed Consolidated Financial Statements assuming the Company will continue as a going concern.

We do not have adequate liquidity, including access to the debt and equity capital markets, to operate our business over the next 12 months from the date of issuance of this Form 10-Q. The Company had a working capital deficiency of $5.6 million as of March 31, 2018. As a result, our short-term business focus continues to be to preserve our liquidity position. Unless we are successful in obtaining additional liquidity, we believe that we will not have sufficient cash and liquid assets to fund normal operations and, as such, there is substantial doubt about the Company’s ability to continue as a going concern for the next 12 months from the date of issuance of this Form 10-Q. In addition, the Company’s obligations under its pension plan exceeded plan assets by $4.2 million at March 31, 2018, including $669,000 of minimum required contributions due over the next 12 months. The Company is in default on its 8¼% Limited convertible senior subordinated notes due 2012 (the “Notes”) and 9½% Subordinated debentures due 2012 (the “Debentures”), which have remaining principal balances of $387,000 and $220,000, respectively. Also, as of March 31, 2018, the Company was not in compliance with the fixed charge coverage ratio or loan turnover covenants related to its Credit Agreement (hereinafter defined), which non-compliance was waived by the Lender. As a result, if the Company is unable to (i) obtain additional liquidity for working capital, (ii) make the minimum required contributions to the defined benefit pension plan, (iii) make the required principal and interest payments on the Notes and the Debentures and/or (iv) attain and maintain compliance with all debt covenants, there would be a significant adverse impact on the financial position and operating results of the Company. The accompanying financial statements do not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amounts and classification of liabilities that may result from the outcome of this uncertainty.

The Company is seeking additional financing in order to provide enough cash to cover our remaining current fixed cash obligations as well as providing working capital.
